Allegro/P-30
A place to share information about and to get help with your Tiffin Allegro and its P-30 Chevy chassis. I'm amazed at the seemingly infinite combinations of floor plans throughout the years.
Dash Controls
has anyone had to replace their dash AC/Heater controls or have a diagram and can provide some direction. Also has anyone replaced with after market controls. My controls have fallen apart and not sure what goes where on the back. Thanks for your help I have a 1986 Allegro Titan.

Even if its expensive, the exact replacement part IS SO MUCH EASIER to replace. The make and model of the chassis/frame like if it is what was used in an x year x size truck chassis may help you track down the part. Some of those just have a switched resistor bank that controls fan speed which may be hard to replicate. On some GM trucks the switched resistor block (that controlled 3 speed fan) was separate and easily replaced down in the floorboard area NOT in the dash switch.

Can you upload a picture of the control unit? I am not familiar with the Allegro dash panel, BUT, I faced the similar problem with my 85 pace arrow (had a bad fan control switch). Here is what I found: One would think that since the chassis is Chevrolet, it would be a Chevrolet control; well not so sports fans! It ain't even close. I spent some time on google searching for P-30 heater control, Chevrolet heater, one lever heater control,,etc and no luck. Turns out my Pace Arrow used the ARA firewall mounted AC/Heater unit. ARA (long gone out of business) used a complete one lever, multi-button control unit from the 80's Dodge Ram Pickup. Google it and see if it matches what's in your dash panel. If not, the just start googling until you find and image that matches. After I identified the control, I went down to NAPA and was able to get a new fan control switch; works great! Best of luck.

Mine looks just like the picture on the home page without fancy writing, just plane old block letters. Came from a 1991 Dodge Ram truck. Search Mopar heat/AC control Ass.
